FURNACE FOR THE MANUFACTUREDFSTEEL,

Specication of Letters Patent No. 5,3267, ydated October 9, 1847. l y

To all whom t may concern.' v

Be it known that I, SIMEON BROAD- MEADOW, of the city, county, and State of New' York, have made a new and useful Improvement in the Construction of Furnaces for Converting Iron into Steel by Cementation. y V v In the ordinary mode of constructing the converting furnace, the iues from thev grate pass upward on each side of the coffer or oven, and deliver themselves into an arch over the top of the Oven, which arch has numerous flues opening into the dome, al-

lowing a vast quantity of heat to escape, the` llame being from four to six feet above the top of the arch, inside the dome, and leaving Y leXpending itself, and diffusing the heat more enerally than by the old lan. When the uel used in firing has partially spent itself, I nearly close the damper, by which means `the `heat is forced intoy the V.Side or dead flues, and enables me to obtain a greater lvamount of heat from lthe same fuel, which would otherwise escape throughthe chimney. 1

In the accompanying drawing, Figure l` Ais afront view of the converting furnace,

the temporary brickworkused `to inclose the cofler and end flues, and likewise those that inclose the dead ue's A1A, the arch, D, and

the stack, G, being removed, B being the covering of the iron to be converted, consisting of a layer of lire-clay, and a layer of -sand, removed and replenished at every charge of the. convertory.

orl oven, with the dead or stopped flues on one side. f

Having thus fully described thenature'of my improvements in the construction Of the furnace forl converting iron into steel lby cementatlonZ-what I claim ytherein as new,

and desire to secure by Letters Patent, is-

The closing Of thev side flues at the top,

Fig. 2 is an elongated view of the coffer `and passing the smoke andame through 'l flues at eachend ofthe oven, into and along f the arch to the center, and thus into the.

chimney.
